Pull Request Overview

This PR introduces rule GCI108 "Prefer Append Left" which recommends using deque's appendleft() method instead of list.insert(0, val) for inserting elements at the beginning of a list in Python. The rule is aimed at improving performance and reducing carbon emissions when performing frequent insertions at the start of a list.

• Adds complete rule specification documentation with performance analysis and carbon emission measurements
• Defines rule metadata in JSON configuration file
• Updates project documentation to include the new rule

This is an extremely long sentence that's difficult to read. Consider breaking it into multiple sentences or moving the deque definition to a separate paragraph.

Suggested change

	We'll analyze the impact of inserting 10**6 elements at index 0 of a list and compare this with inserting the same number of elements using a deque (deque stands for Double-Ended Queue. It is a data structure that allows adding and removing elements from both ends efficiently. Unlike regular queues, which are typically operated on using FIFO (First In, First Out) principles, a deque supports both FIFO and LIFO (Last In, First Out))
